When Jian Pengfei met Cao Zhenhai, the latter was writing a report in the office.

After learning about his purpose, Cao Zhenhai smiled and shook his head: "Mr. Jian, I am very sorry. Thank you for your praise and respect for me. However, I am completely disappointed with the lithium-air battery, so please go back."

Jian Pengfei frowned and said, "Academician Cao, before I came to you, I had visited many experts in the battery industry, but their attitude was almost the same as you. When I heard about lithium-air batteries, I refused me.

I want to know why you are not optimistic about lithium-air batteries like this. It has theoretical support, right?"

Cao Zhenhai opened the thermos and drank some water, and said slowly: "Lithium-air battery... is just a beautiful vision.

There are many companies that have used lithium-air battery technology, including domestic and foreign battery energy giants. After all, the theoretical energy density of lithium-air batteries is too high.

But they all failed in the end without exception.”

Cao Zhenhai said: "There are many problems and difficulties in lithium-air batteries. Lithium crystal branches are a hurdle that cannot be avoided. Before the battery has been solved, the huge safety hazards had been encountered.

In addition, there are a lot of side reactions in the battery and cannot be solved. It is meaningless to make a lithium-air battery.

Anyway, I can’t chew the hard bone of lithium-air batteries and I don’t plan to touch them anymore.”

Jian Pengfei repeatedly persuaded him that even if he offered a high salary, Cao Zhenhai still shook his head and refused to agree. Helplessly, Jian Pengfei sighed slightly in his heart and prepared to say goodbye and leave.

But before he left, Cao Zhenhai called him: "You wait first."

"Academician Cao, have you changed your mind?"

"No, I didn't change my mind, I just remembered something." Cao Zhenhai hesitated for a moment and said, "I have no interest in lithium-air batteries, but I can recommend a friend who has a persistent belief in lithium-air batteries to you.

Although his resume is average, his ability to work is pretty good and he is suitable for working in companies like you.

Moreover, even if the whole world says that lithium-air batteries are not good, it will definitely be an exception."

Jian Pengfei's eyes lit up slightly: "Thank you so much!"

...

In the evening, He Tianqiang returned home with his tired body after get off work, fell on the sofa and closed his eyes and rested.

He Tianqiang is 46 years old this year and works in a lithium battery research institute in Yanjing.

As a supporter of the lithium-air battery theory, He Tianqiang feels very tired and uncomfortable.

But there is no way. Lithium-air batteries are now considered impossible to realize by the industry. Although he supports the lithium-air battery theory, he does not dare to blatantly study it. He can only post articles on some academic forums when he is fine, expressing his optimism about lithium-air battery technology.

"Oh, when will this kind of day end..." He Tianqiang opened his eyes and rubbed his eyebrows, his eyes were a little distracted.

At this time, my wife, who was cooking in the kitchen, came to the living room, sat next to He Tianqiang, patted his thigh and asked, "Old He, I'll tell you something."

"Well, tell me." He Tianqiang nodded, sat up straight, picked up the tea on the table and took a sip.

The wife said: "Our boy had a girlfriend. I am quite satisfied with that girl. I think they should be able to get together, so my son is about to get married. I think it's time to buy a house."

"Buy a house..." He Tianqiang muttered. In his impression, the housing prices in Yanjing were unattainable.

My wife said: "I went to a sales center this morning and found a house with a good location and affordable price. The down payment would cost about 2.75 million yuan."

"2.75 million... Is the family's savings enough?"

"It's just not enough, it's still about 800,000 yuan."

He Tianqiang felt a little hurt when he heard this, but as the head of the family, his son wanted to get married and buy a house. He couldn't say weakly that, right?

So, He Tianqiang had to force himself to say, "I'll find a way to deal with money..."

But his wife saw his compulsion at a glance and said, "What can you do? Your annual salary of 300,000 yuan will cost you enough food and drink, and it will take at least three or four years to make up 800,000 yuan. By then, the housing prices will definitely rise again.

What I think is, if it really doesn’t work, I will sell the house we live in now, and then go to your dormitory to buy a house for my son. What do you think?"

He Tianqiang smiled bitterly and said, "I don't care. It's the same wherever I live. I'm afraid that the boy will disagree. You don't know his personality, you must be strong."

Wife: "It depends on us whether we do it or not. It is another matter whether he agrees or not. When the matter is settled, he will not agree."

He Tianqiang sighed, "Okay, then you can handle this matter."

At some point, He Tianqiang felt that this person was so tired of living.

People like him spend their entire lives revolving around houses. When they were young, their parents bought houses. When they grew up, they wanted to buy houses, and when they were older, their son wanted to buy houses.

The struggle for most of my life has been to make wedding dresses for the house and become a real house slave, but I have to do it. It makes people feel helpless and sad.

Dingling dong, Dingling dong...

At this moment, the doorbell at the door suddenly rang. The doorbell was connected to the access control system downstairs. It often rang. It was probably because the neighbor's people pressed it wrong, so He Tianqiang's wife walked to the door, closed the bell, and opened the door downstairs at the same time.

However, not long after, a knock on the door sounded.

He Tianqiang: "Who is it?"

He Tianqiang's wife replied, "I don't know, I thought the person downstairs was from the neighbor's house just now."

As she said that, she quickly walked to the door and opened it. She saw a man in a suit standing straight at the door. When she saw her smiling, she asked, "Is this the home of Professor He Tianqiang?"

“Yes, are you?”

"My name is Jian Pengfei, I am from Black Bone Group. Academician Cao Zhenhai introduced me. I came to see Professor He specifically. I want to talk to him about some battery issues. I don't know if Professor He is at home?"

"Okay, don't stand outside, please come in quickly." He Tianqiang's wife responded and shouted to the living room: "Old He, look for you."

After Jian Pengfei entered the He family, He Tianqiang's wife hurriedly went to pour water, while Jian Pengfei sat on the sofa and started chatting with He Tianqiang.

After Jian Pengfei's self-introduction ended, He Tianqiang asked: "Mr. Jian, don't you know what important things are for me?"

Jian Pengfei said: "That's right, because our company plans to conduct research in the battery field and focus on lithium-air batteries, so our boss sent me to find relevant professionals.

I went to find Academician Cao Zhenhai before, but he refused, but he recommended Professor He to me.

So, I hurriedly came to visit you according to the address given by Academician Cao."
